The bus service was awesome, but that's because the resort is 1/4 open. Not very many people on the buses and the wait to catch a bus to the park was very short.
The Arcade is near the rear exit to the main pool. It's in the Art of Animation Hall and it's a really nice one. All the latest/greatest games and a huge selection.
It's across from the last few people in this line towards the rear of the picture.
Awesome, thanks for the info!! Super excited!!
